    TLDR Using facial sunscreen and moisturizer may increase the risk of frontal fibrosing alopecia.
    This systematic review and meta-analysis investigated the relationship between frontal fibrosing alopecia (FFA) and the use of cosmetic and personal care products. Analyzing data from 9 studies with 1,248 FFA patients and 1,459 controls, the study found significant positive associations between FFA and the use of facial sunscreen (OR 3.02) and facial moisturizer (OR 2.20), particularly in men for moisturizers (OR 5.07). No significant associations were found with other hair or facial products. The findings suggest that leave-on facial products, especially those with UV-protecting chemicals, may contribute to the development of FFA, indicating a potential environmental etiology.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
